Do you use formal pencil and paper pre-assessments prior to starting a math unit? My thoughts are mixed on this and am wondering what others are. I have found that after the joy and celebration of successfully completing a unit, my kids are hit with this pre assessment that often no one passes. So they go from feeling great one day to feeling really insecure the next with the pre assessment n the new unit. I am giving district created math assessments but am wondering if there isn't a better way to determine prior knowledge and effectively use pre-assessments. For all you middle and high school math teachers, what do you do? Thanks !!
